Membrane-based gas separations are energy efficient processes; however, major challenges remain to develop high-performance membranes enabling the replacement of conventional separation processes. Herein, a new fluorinated MOF-based mixed-matrix membrane is reported, which formed by incorporating MOF crystals into selected polymers via facile approach. By finely controlling molecular transport in channels through apertures tuned metal pillars and at MOF-polymer interfaces, resulting exhibit...
Membrane-based separation is poised to reduce the operation cost of propylene/propane separation; however, identifying a suitable molecular sieve for membrane development still an ongoing challenge. Here, successful identification and use metal-organic framework (MOF) material as fillers, namely, Zr-fum-fcu-MOF possessing optimal contracted triangular pore-aperture driving efficient diffusive propylene from propane in mixed-matrix membranes are reported. It demonstrated that fabricated...
Membrane-based separation of combined acid gases carbon dioxide and hydrogen sulfide from natural gas streams has attracted increasing academic commercial interest. These feeds are referred to as "sour," herein, we report an ultra H2S-selective exceptionally permeable glassy amidoxime-functionalized polymer intrinsic microporosity for membrane-based separation. A ternary feed mixture (with 20% H2S:20% CO2:60% CH4) was used demonstrate that a membrane provides unprecedented performance under...
Membrane-based separations offer great potential for more sustainable and economical natural gas upgrading. Systematic studies of CO
We demonstrated here a novel and facile synthesis of two-dimensional (2D) covalent organic thin film with pore size around 1.5 nm using planar, amphiphilic substituted heptacyclic truxene based triamine simple dialdehyde as building blocks by dynamic imine bond formation at the air/water interface Langmuir–Blodgett (LB) method. Optical microscopy (OM), scanning electron (SEM), transmission (TEM), atomic force (AFM), all unanimously showed large, molecularly free-standing membrane that can be...
Abstract Glassy polyimide membranes are attractive for industrial applications in sour natural gas purification. Unfortunately, the lack of fundamental understanding relationships between chemical structures and their transport properties presence H 2 S constrains design engineering advanced such challenging applications. Herein, 6FDA‐based with engineered were synthesized to tune CO /CH 4 S/CH separation performances plasticization properties. Under ternary mixed feeds, controlling polymer...
Defect engineering in metal–organic frameworks (MOFs) is an emerging strategy that can be used to control physical or chemical characteristics of MOFs, including adsorption behavior and textural, mechanical, conductive properties. Understanding the impact defects on textural properties stability MOFs imperative development with tunable defect sites. In this work, systematic measurements were performed three adsorbate molecules (SO2, benzene, cyclohexane) investigate changes pore size...
Understanding the effects of presence water vapor and other gas impurities (such as SO2 O2) in flue on sorbent performance is critical to properly evaluate use metal organic frameworks for realistic postcombustion CO2 capture. Grand canonical Monte Carlo calculations were performed investigate H2O, O2, adsorption CO2/N2 separation using ZIF-68. The mechanisms these also investigated by density functional theory calculations. H2O affects ZIF-68 two opposite ways: negative effect competitive...
Density functional theory (DFT) calculations are performed to investigate the effect of functionalized linkers on CO2 binding in zeolitic imidazolate frameworks (ZIFs). Three typical ZIFs with different considered: ZIF-68 bIM linker (C6H6 group), ZIF-69 cbIM (chlorine and ZIF-78 nbIM (nitro group). Compared linker, charge distributions have been significantly changed by substitution groups proved positive effects enhance capacity CO2. The withdrawal electronic from leads enhanced acidity for...
Metal organic frameworks (MOFs) represent a new kind of porous solid and have shown promising potential for carbon dioxide (CO2) capture separation.
